Groundwater Pollutant Transport Research Of An Electric Plant Based On GMS

Minhang District of Shanghai is a typical pollution induced water shortageplace with a rich groundwater quantity but poor quality.Taking the Water treatmentstation of a electric plant of Minhang Distric, this article use GMS to simulate thepollutant transport situation based on the water level data,Hydrological geologicalreport and so on.According to the results,the author provide a specific method oflater period management and make some analysis,providing a reference for thegroundwater recovery of this study area.The study results as follows:1)Conductivity of aeration zone of the research area is from2.36E-04~5.31E-04cm/s; conductivity of phreatic aquifer is6.51E-5cm/s, waterstorage coefficient is1.76E-03.2)Seepage damage or failure to take prevention measures,pollutant will go intothe groundwater from the Penetration point,meanwhile will transport to thedownstreams of the groundwater.3)In this study,we find that the results of using more wells is not better thanthat of using one well in saving pumpage.Quantity of pumping wells:under thesame conditions of acquifer and pollutant, Purification and pumping time will beshortened by using bigger pumpage.For short target management and low pollutantconcentration,we shall use big pumpage.Add filling wells will shorten the recoverytime of polluted groundwater.In some areas,we can add fillingwells upstreams toforce the groundwater.. The groundwater solute transport model established in this article accuratelyreflects the actual characteristics of the study area groundwater systems andtransport situation. It provides a scientific basis for the groundwater qualityforecasting and pollutant abatement.
